Smucker’s move comes as an increasing number of food makers have been lowering or eliminating trans fat from its products. In December, New York became the first U.S. city to ban trans fat at restaurants and fast-food establishments that use trans fats to increase the shelf life and flavor of foods.

A bill introduced last month in Philadelphia City Council would ban restaurants and food service establishments from using artificial trans fats and Cleveland’s council has talked about looking into a ban.

Crisco still has a small amount of artificial trans fat but the U.S. Food and Drug Administration allows any product with less than 0.5 grams trans fat per serving to list zero grams trans fat in its nutrition facts.

Badertscher said the new Crisco formula is well below the FDA guidelines.

Introduced in 1911, Crisco was the first shortening product made entirely of vegetable oil and made its reputation on having lower saturated fat levels than butter, coconut oil, palm oil or lard, she said.

The company introduced a zero grams trans fat formula in 2004 sold in a green can. That formula, which used sunflower oil and was more expensive, has been discontinued.

The new formula of Crisco uses less partially hydrogenated cottonseed and soybean oils and more fully hydrogenated cottonseed oil — which contains no trans fat.

Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

Hydrogenated oils are what gives shortening its semisolid consistency and high performance cooking attributes, according to the company.

The company placed an emphasis on reducing the trans fat content without increasing saturated fats, Badertscher said.

That’s a positive, said Lisa Cimperman, clinical dietitian at University Hospitals Case Medical Center in Cleveland.

“It is an improvement from the standpoint that we know reducing the amount of trans fat you take in can reduce your risk for cardiovascular disease,” Cimperman said.

She warned, however, not to believe that anything with zero grams trans fat should be consumed in large quantities.

“What do you use Crisco for — to bake cookies?” she said. “This whole trans fat issue is not the end all be all of good nutrition.”

Other food makers that have recently removed or lowered trans fat include Campbell Soup Co., which is working to revise some varieties of Chunky soup and SpaghettiOs with meatballs. Kraft Foods Inc. has removed trans fats from Triscuits and Oreos.

Smucker, based in Orrville, Ohio, makes and sells fruit spreads, peanut butter, shortening and oils, ice cream toppings foods and drinks in North America. Its brands includes Smucker’s, Jif, Crisco, Pillsbury, R.W. Knudsen Family, Hungry Jack and Martha White in the United States and Robin Hood and Bick’s in Canada.
